Title:Perceptual Studies for Foveated Light Field Displays

Abstract: The human visual system can resolve higher spatial frequencies in the fovea
than in the periphery. This property has been harnessed by recent 2D foveated
rendering methods to reduce computation cost while maintaining perceptual
quality. Inspired by this, we have conducted psycho-physical experiments to
study foveation of human visual systems for 4D light fields and evaluate our
prototype system described in [Sun et al. 2017].
We measure, for the first time, the blur detection/discrimination and light
field depth perception thresholds in up to 15 degree of visual eccentricity,
and reject the idea of replacing the peripheral rendering with 2D billboards -
4D light fields are still required. The psycho-physical data can also guide
other foveated rendering approaches.
